FUEL AND SPARK CONTROLLING MECHANISM.

Specification of Letters Patent.

Patented Dec. 26, 1916.

Application filed May 18, 1915. Serial No. 28,965.

To all whom it may concern:

Be it known that I, JOEL BENJ. DALBEY, a citizen of the United States, and resident of Nevada, in the county of Story and State of Iowa, have invented a certain new a fuel and spark controlling mechanism of simple, durable and inexpensive construction.

A further ob ect is to provide in such a device mechanism for controlling the flow or ignition of fuel to a generator, which mechanism is also adapted to control the flow of fuel to the burner.

Still a further object is to provide such a. device, the mechanism of which is adapted to operate contact points by closing an electric circuit.

Still a further object is to provide a device of the class mentioned, comprising a single installation in convenient form for controlling generating fuel and burning fuel for one or for a plurality of lamps, and for controlling contact points adapted to be in an electric circuit employed for causing a spark for igniting the generating fluid.

My invention consists in the construction, arrangement and combination of the "arious parts of the device whereby the objects contemplated are attained as hereinafter more fully set forth pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation partly in section of a fuel and spark controlling mechanism embodying my invention. Fig. 2

a shows a horizontal sectional view taken on the line 22 of Fig. 1, one of the valves being shown in section taken on a lower plane than that of the main portion of the view. Fig. 3 shows a vertical sectional view taken on the line 3-3 of Fig. 2, and Fig. 4 shows a front elevation of the device as installed on a wall or other support.

My improved fuel and spark controlling mechanism is designed to be used in connection with a lamp or lamps in a system, such for instance, as that shown in my application for Patent Number 14,830, filed March 16, 1915. I have, however, in my present drawings, shown only the apparatus or installation adapted to be mounted on a wall or other support, and designed for controlling fuel, and the contact points forming part of an electric circuit, which circuit is employed for producing a spark for igniting the fuel for generating gas.

In the exemplification of my present invention, illustrated in the drawings filed herewith, I have employed the reference numeral to indicate generally the up right member of a frame. At the upper and lower ends of the member 10 are forwardly extending frame members 11. At the forward portion of the frame 10 is a plate 12 secured to the members 11 and adapted to fit against the wall or other support.

The members 11 are provided with extensions 13 adapted to be secured to a support by means of screws 1 1. The plate 12 may be detachably mounted on the frame by means of similar screws 14.

Suitably supported on the frame is an upright tube or pipe 15, having at its lower end a rearward extension 16. On the interior of the extension 16 is a contracted portion 17 having a small central opening 18. The wallof the portion 17 around the opening 18 is inclined from its central portion outwardly and forwardly toward the tube for a purpose which will be hereinafter referred to.

A supply tank 19 is suitably located and is adapted to contain generating fuel. A tube 20 communicates with the supply tank 19 and with the extension 16. The tank 19 may be arranged above the level of the upper end of the tube 15, tially filled with air under pressure.

Communicating with the tube 15, by means of a tube 21, is an air pressure tank 22 closed except for its communication at its "lower end with the tube 21. It will be seen that the pressure of the fuel or air in the tank 19 will tend to compress the air in the tank 22.

Screwed into the wall of the tube 15 in line with the opening 18 is a rod 23 on which or may be par-.

Wardly the tip 25 will enter the opening 18 p for cleaning it.

Above the extension 16 the tube 15 is provided with a plurality of extensions 26.

Communicating with the various extensions 26 are fuel carrying tubes 27, designed to lead to a plurality of lamps for carrying generating fuel thereto.

Suitably mounted on the frame is a main fuel supply tube 28, having a plurality of extensions 29 which preferably lie in avertical plane parallel with the plane in which the extensions 26 are located. Communicating with the various extensions 29 are fuel supply tubes 30 designed to lead to a plurality of lamps.

Slidably mounted in the plate 12 and the frame between the respective extensions 26 and the respective extensions 29, are a plurality of sliding or push rods 31, preferably arranged in. vertical series. On the rods 31 outside the plate 12 are suitable heads 32. Each rod 31 is formed with two spaced notches 33, adapted to be entered-by a spring 3 1 mounted on the frame.

In each of the extensions 26 and 29 is a valve 85 having a stem 36 projecting in a horizontal plane toward the vertical plane in which the rods 31 lie. the stems 36 are upright extensions 37, normally held in upright position by springs 38.

On each rod 31 is a finger 39 extending laterally from the rod and, having at its outer end a rearward extension 10. On each rod 31 forwardly of the finger 39 is a laterally extending linger 11, having at its outer end a forward extension 42. The eX- tension 12 is of spring metal and has at its forward end a downwardly curved portion 13.

Suitably mounted on the frame adjacent to the portions 13 are contact points 14: adapted to be engaged by the portions 43 in one position of the movement of the rods 31. it will be understood that the portions 13 are of suitable conducting material and that said portions 13 form contact points, and that in the lighting system, of which my present device is designed to form a part, the portions 4L3 and the contact points 4: are designed to be included within an electric circuit having gaps at proper points adjacent to the lamps for causing a spark when the circuit is closed by the contact of the members 13, and the points 14 for lightine' generating fluid or lighting lamps after generating.

The operation of my device will now be described. i It will be understood that my improved device, as herein described, is designed to be installed in connection with a lamp or lamps as part of the lighting system, which system should include a suitable tank for supplying fuel to the tube 28 and an electric circuit as above mentioned. When thus installed the operation of my device is as follows: The rods 31 are designed to ordinarily stand in position with the end of the On the ends of spring 3. received in the forward notch 33. r"; v

s the middle and neutral position of ds, and is the position illustrated by econd from the top and the lowermost shown in Fig. 1, i i hen it is desired to one of he lamps, the 31 adjacent to the extensions 26 and 29 connected with the lamp in question are first pushed inwardly to the position shown by the upper rod 31 in Fig. 1. When in such position the finger 4-1 will engage the extension 37 of the stem valve in the extension 26, adjacent to the rod 31 moving it rearwardly e ainst the pressure of the spring 38, for ening said valve and allowing the pre sure of the in the tank to force the generating fluid through the tube 27 to the proper lamp for generating purposes. this connection it will be noted that the pres sureof the in the tank 22 acts automatically on the alcohol or other generating fluid. The spring 38 on the stem of the valve tends to return the rod 31 to its closed position.v ihe size of the opening 18 is so small that while the head 32 is held at its inner limit of movement very little fuel is supplied to the tube 15, so that there is little danger of an overflow of generating fluid being forced to the lamp for generating the main fuel supply tube. When the rod has been held at its inner limit of movement for a proper time for supplying generating fluid to the lamp, it is then pulled out to its outer limit of movement, as illustrated by the third rod from the top in Fig. 1, to position with the spring 3 1 received in the inner notch 33. During the outward movement, the points 43 and contact for closing the electric circuit, and causing a spark for generating the alcohol or other fluid. The outward movement of the rod 31 causes the finger 39 to engage the extension 37 of the valve in the adjacent extension 29 swinging it forwardly as illustrated by dotted lines in Fig. 3 for turning on the gasolene or other fuel supply.

It will be noted that the upper end of the extension 3? stands below the member 410, as shown by said dotted lines, when the rod 31 is at its outer limit of movement, so that the spring 38 will not move the rod 31 inwardly. The rod 31 is left pulled out as long as it is desired to keep the lamp lighted.

When the rod is at its outer limit of move ment, the member 13 stands clear of the contact point 1 1, as illustrated by the member 13 on the third rod 31 from the top in Fig. 1.

The operation just described may be re peated for each of the lamps included in the installation.

It will be noted that the members 17 are so constructed that they are inclined rearwardly in the extensions 26, so that foreign matter or sediment in the alcohol or other generating fluid will not tend to collect immediately in the opening 18, but will drop downwardly to the bottom of the extension 16 and around the inclined portions of the members 17. If, however, during the use of my device, the opening 18 should become clogged at any time, the heads 32 may be unscrewed from the rods 31 and the plate 12 removed, whereupon the rod 23 may be screwed inwardly for causing the portion 25 thereof to enter and clean the openings 18.

It will be understood that 1n my drawings, I have simply illustrated one form of myinvention and that many modifications thereof may be made, and it is my intention to cover by this application any such changes which may be included within the scope of my claims. I

It will also be understood that my device may be used for lamps, stoves, burner or other purposes.
